CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 339,358, dated April 6,1886.

Application filed February 3, 1886. Serial No. 190,724.

To all whom it may concern:

Be it known that we, WILLIAM H. ADAMS, James D. Fnn'rnonsnn, and ALBERTLAW- TENSLAGER, all of Albany, in the county of Albany and State of NewYork, have invented a new and useful Improvement in (lac Couplings, ofwhich the following is a full, clear, and exact description.

Reference is to be had to the accompanying 1o drawings, forming a partof this specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional side elevation of our improved car coupling,part being broken away. Fig. 2 is a front elevation of one of thedrawheads, the coupling-links being shown in section. Fig. 8 is asectional plan view of a part of the coupling, taken through the line ana:, Fig. 2.

The object of this invention is to improve the construction of thecar-couplings for which Letters Patent No. 305,261 were issued to usSeptember 16, 1884, in such a manner as to make them more reliable inoperation.

The invention consists in the construction and combination of variousparts of the carcoupling, as will be hereinafter fully described andclaimed.

A represents the draw-head of the car- 0 coupling, which is made with aflaring mouth,

so that the coupling-link I5 will enter it with certainty.

The coupling-head A is designed to be secured to the car in the ordinarymanner. In

5 the top of the coupling-head A is formed a slot, (3, of sufficientsize to allow the couplinghook D to be readily inserted and removedthrough it. In the rear end of the hook D is formed a short slot, E, toreceive the pin F,

40 by means of which the said hook is secured in place. The pin F can hekept in place by a key or other suitable means, and should be soarranged as to allow the eonplinghead A to have the necessary play.

5 The coupling-hook I) is made with two hooks, G H, upon its lower side,which enter slots I J in the lower side of the draw'head A. The rearhook, H, is made long, so that it will never be raised out of its slot Jwhen the car-coupling is in use.

The forward upper corner of the coupling- (No model.)

hook D is beveled or inclined to fit against the beveled seat K at theforward end of the slot 0, so that a draft strain upon the said hook.will hold it more firmly in place and prevent it from jumping upward andreleasing the coupling-link.

The forward side of the forward hook, G, is inclined or rounded, so thatthe hook D will be raised by the contact of the coupling-link B when thecars are run together to allow the end of the said link to pass theforward hook, G, when the coupling-hook Ddrops back into place and thecars are coupled, the forward hook, G, passing through the said link B.

The inclined forward side of the forward hook G rests against aninclined seat, L, at the forward end of the slot I. The forward side ofthe rear hook, H, is inclined or rounded, and rests against an inclinedseat, M, at the forward end of the slot J, so that the coup ling-hook Dis provided with four bearingpoints, the inclined seats K L M, and thepin F.

\Vith this construction each draw-head A is permanently provided with acoupling-link,

B, the inner end of which is held by the rear hook, H, of the doublehook D, and which, when two cars are run together, enters the draw-headof the adj accnt car, raises the coup 8o ling-hook D,and passes andengages with the forward hook, G, so that the draft strain will besustained by two independent links, either of which will sustain thedraft strain should the other link be broken.

With this construction, should both the links B be broken, the cars canbe coupled by an ordinary coupling-link, the ends of which engage withthe forward hooks, G, of the double hooks D, and with this arrangementthe coupo ling will still be automatic. v

In recesses in the sides of the draw-head A, upon the opposite sides ofthe shank of the coupling-hook D, and in front of the pin F, are placedloose weights N, the forward parts of which rest upon the inner end ofthe coupling-link permanently connected with the said draw-head, andwhich should he of sufficient gravity to hold the other end of the saidlink raised, so that it will enter the drawhead of an adjacent carautomatically. The forward movement of the weights N is prevented byribs 0, formed upon the inner surfaces of the sides of the draw-head A.lhe links B are held against the rearward push when the cars are runtogether, and the forward ends of the said links strike the hooks of theadjacent cars by shoulders P,formed upon the inner surfaces of the sidesof the draw-head A.

Having thus fully described our invention, we claim as new and desire tosecure by Letters 10 Patent l. The combination, with the draw-headformed with the open flaring mouth, the top slot, 0, the bottom slots, IJ, the weight-recesses on its inner sides, and the ribs 0, pro- 15jeeting from said inner sides in front of the said recesses, of theweights N in said re eesses, the pin F in rear of the recesses, thecoupling-hook D, having a shank projecting rearward between vthe ribs 0to its pivot-pin 20 F, and having the two hooks G H at its forwardend,and the permanent link B, substantially as set forth.

2. In a car coupling, the combination, with the draw-head A, havingslots 0 I J, and beveled seats K L M at the forward 25 ends of the saidslots, of the double hook D, beveled at the upper part of its forwardend, and having a short forward hook, G, and a longer rear hook, H, onits lower side, and the fastening-pin F, substantially as herein shownand described, whereby two couplinglinks can be connected independentlywith the said draw-head, as set forth.
